Among the figure: sensor 1, inspection platform 2, gas cabinet 3, controller 4, upper-position unit 5, gas cabinet piston 6, guided wave cone 7, sensor outer housing 8, packing material 9, high energy ripple sounding body 10, outgoing cable 11, controller housing 12, display device 13.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
There is coal gas gas cabinet 3 inside, the coal gas top layer is provided with a gas cabinet piston 6, and the top of gas cabinet 3 is provided with inspection platform 2, and the sensor 1 in the measuring device is installed on the inspection platform 2, this sensor 1 is connected with controller 4 by cable, and controller 4 is connected with upper-position unit 5.
As preferred version, sensor 1 is selected the explosion-proof type large-power supersonic transducer, perhaps in the explosion-proof type radar levelmeter.
Controller 4 comprises controller housing 12 and is installed in display device 13 on the controller housing 12, also is equipped with in this controller housing 12 to be used to single-chip microcomputer and the control circuit changing and control.Single-chip microcomputer is connected with display device, change-over circuit, warning output circuit respectively, wherein change-over circuit is connected with the explosion-proof type large-power supersonic transducer, single-chip microcomputer also is connected with upper-position unit, and single-chip microcomputer can be given upper-position unit with the various parameter real-time Transmission of gas cabinet, convenient monitoring.4-20mA standard signal and RS485 digital communication that controller can provide upper-position unit to need, and can be according to the situation output control signal corresponding of survey parameter.Be provided with parameter calculating module in the single-chip microcomputer of controller, output again after calculating through computing module after data are gathered, and show by display device.Upper-position unit is meant the control computer or the programmable controller of custom system.
Present embodiment describes with the explosion-proof type large-power supersonic transducer.
The explosion-proof type large-power supersonic transducer is installed on the gas cabinet inspection platform, and guided wave cone 7 wherein places the below, and high energy ripple generation body 10 places shell 8 inside of this ultrasonic transducer, and high energy sound wave emission direction is aimed at the gas cabinet piston upper surface.High energy ripple generation body 10 is the parameters according to the high energy sound wave, the metal body that carries out manufacturing.Between high energy ripple generation body 10 and the shell 8 packing material 9 is arranged, this packing material 9 has the function of explosive-proof protector, is arranged on the outgoing cable 11 of the high-power transducer end of explosion-proof type and is connected with change-over circuit in the controller.The high efficiency vibrational mode is adopted in the inside of this explosion-proof type large-power supersonic transducer, utilizes the high energy technology of acoustic wave, finishes the transformation of energy of electric energy to ultrasound, ultrasound to electric energy.Adopt the high energy technology of acoustic wave, transducer has higher sensitivity and antijamming capability and stable performance.The explosion-proof type large-power supersonic transducer is regularly launched ultrasonic pulse under the excitation of pulse signal, ultrasonic pulse arrives gas cabinet piston face back reflection returns, and is received and convert to electrical signal by transducer, delivers to controller and handles.
